Researchers design and test a waste-heat recovery system, illustrated here, that attaches to a car tailpipe and converts heat from exhaust into energy. The fanned grooves on the outside of the pipe are the cold side of the device’s heatsink and the triangular components inside the pipe are plate-fin heat exchangers.

Most fuel in gas-powered vehicles is wasted as heat, but a new study reveals a way to convert this lost energy into electricity.
Researchers have developed a thermoelectric generator that captures exhaust heat and transforms it into usable power. Unlike previous systems, which are heavy and require extra cooling, this new design is lightweight, efficient, and…
